I would venture to say around $1200 total. Maybe $1400, but no more than that.
From what it looks like, the cab is significantly used and not in like-new condition. Road cases are a "take-it or leave-it" item for me, and I try not to factor them into any used purchases, unless of course I specifically was searching for one. Just because it "comes with it," doesn't mean I'll pay more for that extra weight. This pricing is also based on the fact that the head probably was owned by more than its original buyer and doesn't come with a transferrable warranty.
